 ## Features
 
 - Local HTTP/HTTPS/SOCKS server with authentication support
-- VMess, VLESS, Shadowsocks, Trojan, Snell, TUIC, Hysteria protocol support
+- VMess, Shadowsocks, Trojan, Snell protocol support for remote connections
 - Built-in DNS server that aims to minimize DNS pollution attack impact, supports DoH/DoT upstream and fake IP.
 - Rules based off domains, GEOIP, IPCIDR or Process to forward packets to different nodes
-- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node
-  based off latency
-- Remote providers, allowing users to get node lists remotely instead of hard-coding in config
+- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node based off latency
+- Remote providers, allowing users to get node lists remotely instead of hardcoding in config
 - Netfilter TCP redirecting. Deploy Clash on your Internet gateway with `iptables`.
 - Comprehensive HTTP RESTful API controller
 
-## Dashboard
+## Wiki
+Configuration examples can be found at [/docs/config.yaml](https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/docs/config.yaml), while documentation can be found [Clash.Meta Wiki](https://clash-meta.wiki).
 
-A web dashboard with first-class support for this project has been created; it can be checked out at [metacubexd](https://github.com/MetaCubeX/metacubexd).
+## Build
 
-## Configration example
+You should install [golang](https://go.dev) first.
 
-Configuration example is located at [/docs/config.yaml](https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/docs/config.yaml).
-
-## Docs
-
-Documentation can be found in [Clash.Meta Docs](https://clash-meta.wiki).
-
-## For development
-
-Requirements:
-[Go 1.20 or newer](https://go.dev/dl/)
-
-Build Clash.Meta:
+Then get the source code of Clash.Meta:
 
 ```shell
 git clone https://github.com/MetaCubeX/Clash.Meta.git
 cd Clash.Meta && go mod download
-go build
 ```
 
-Set go proxy if a connection to GitHub is not possible:
+If you can't visit github,you should set proxy first:
 
 ```shell
 go env -w GOPROXY=https://goproxy.io,direct
 ```
 
-Build with gvisor tun stack:
+Now you can build it:
+
+```shell
+go build
+```
+
+If you need gvisor for tun stack, build with:
 
 ```shell
 go build -tags with_gvisor
 ```

+```shell
+$ systemctl enable Clash-Meta
+```
+
+Launch clashd immediately with:
+
+```shell
+$ systemctl start Clash-Meta
+```
+
+### Display Process name
+
+Clash add field `Process` to `Metadata` and prepare to get process name for Restful API `GET /connections`.
+
+To display process name in GUI please use [Razord-meta](https://github.com/MetaCubeX/Razord-meta).
+
+### Dashboard
+
+We also made a custom fork of yacd provide better support for this project, check it out at [Yacd-meta](https://github.com/MetaCubeX/Yacd-meta)
+
+## Development
+
+If you want to build an application that uses clash as a library, check out the
+the [GitHub Wiki](https://github.com/Dreamacro/clash/wiki/use-clash-as-a-library)
+
+## Debugging
+Check [wiki](https://github.com/MetaCubeX/Clash.Meta/wiki/How-to-use-debug-api) to get an instruction on using debug API.
